To all who/m .it may concern i will slide on said pivots which passVthere- Y Be it known that we, .lit-on Wanne, a suhl through to connectthe valves, in such maniect of the Emperor of Greruiany` residing at No.172 Bergen street, in the city of New arlt. county ci' Essex, and Stateot' New Jersey, :uid JULIAN E. Hilursox, a citizen of the United States,residing at No. 145 Fairmont avenue, in the city of Newark, countv ofEssex, State of New Jersey, have madecertain new and useful InventionRelating to Pipe-Cleansing Devices, of which the following is aspecification, reference being made to the accompanying drawings, which.term a part of the same.

This invention relates to an apparatus for cleaning 'tubes or pipes ofeither flexible or rigid material and is particularly adapted for use incleaning flexible pipe or hose such as is used in breweries forconveying beer.

The cleaning device as shown may consist of a cleaning brush which isadapted to enter the circuit of pipe and to be forced through the sameand simultaneously rotated by the pressure o1 the wat-er or other fluidused for cleansing purposes. The cleaner may also operate thecontrolling `mlvedevice as to reverse the direction of the waterpressure and force the cleaner baclragain around the pipe circuit whichal.- ternating action is continued until the pipe is thoroughlycleansed.

In the illustrative embodiment of this invention shown in the drawings,Figure 1 is a Vvertical section of the device; Fig. 2 is a ofoss sectiontaken at the line 2-2 of Fig.

, and Fig. 3 is a plan view at the line 3,3

lof Fier. 1.

Referring to the drawings in detail, 1 represents a feed pipe for wateror other cleansing Huid connected to a suitable .casing having a coveror shield 2 made of water tight material having the entrance 55 for thewater pipe 1 which shield is fastened to the device so as to protect thevalve devices which may be of any desired description preferablyactuated by the cleaner for c'ontrolling the alternating or otherdesired admission ot cleansing {iuid to the casing and cooperating pipe.

et is a support secured to the standard-14 into which support is looselypivot/ed a rocking arm 5, at the opposite ends ofwhich are looselypivoted the valves (i and 7 respectively` the apertures in saidroelting'arm being elongated so that said rocking arm ner as to permitthe lineal reciprocation of said valves. The valves G and 7 are providedwith guide pins such as are shown at 8 for the purpose of guiding thereciprocation of said valves in the sleeves 11 and 12, spaces being leftbetween 'said pins for the purpose of permitting the cleansing fluid topass through said spaces and said sleeves as either valve is opened. 9and 10 are cushions or packages on said valves for the purpose ofpermitting them to tit snugly on the'sleeves 11 and 12 when said valvesare closed.

Connecting and communicating with the sleeves 11 and 12, respectively,are the tubes 13 and 15 which tubes are separated from cach other by thestandard 14, in which support is mounted the reciprocating rod 16, thetravel of which is limited. by the pins 3G, 37. On this reciprocatingrod is fixed valves 17 and 18 which are adapted to slide with the rod inthe respective tubes 13 and 15 and thereby alternately open'and closethe discharges 2O and 22, respectively. These discharges are providedwith auxiliary discharge chambers 19 and 21through which.Y and throughthe discharge'pipes 25 and 26, respectively, the used cleansing fluid isdischarged from the said device.

In order to clean a tube by this device a cleansing medium, which isshown in the form of a brush at 33, is inserted in the tube sought to becleaned. One end 'of the tube is then coupled to the device as is shownby the coupling 29 and the other end of the tube is coupled to theopposite end of the device as is shown by the coupling 27, the tube 30,28 being continuous. 'While this cleansing medium may be of any suitableform we prefer one with Winged ends for the purpose 'of giving the samespiral movement in its travel through the tube. These winged ends of thecleansing medium nre designated by the numerals 31 and 32.

Referring to the slide valves, 17, 18 which are shown in section in Fig.2, these valves are provided with passage ways, 34, 35 therethrough forthe purpose of enabling the cleansing fluid to pass through the same.

To operate this device, a continuous tube is fixed thereto as shown, oneend of the tube. being connected with one end of the device and otherend'of thetube being connec-ted `with the other end of the device, thecleaningF medium having been placed in the tube to be cleaned. Thecleansing tluid,

such ufater, is then turned into the device through the pipe l,discharging thereinto at 3T and in the position shown in the druiviug's,tiowing unoerthe valve 7, then thr ugh sleeve 1l. into the tube i3through the age nays ot' the valve l?, and s the Winged end 3l, of thebrush 33, forcing the brush through the. tube in spiral manner. Thebrush will thus continue in its travel the full length ot the tube untilit strikes the cud 24k of the rod lG and will more seid rod and thevalves l' and thereon to a position limited by the pin 37. The valve 1Swill then close the discharge 22 and the valve l? will have moved so asto open the discharge 20. Upon the discharge being closed the wat-erwhich vhas issued through the valve 7 .will force itself against theunder side of valve 6 raising the Same and closing valve 7 therebeing'no resistance against the closing of this valve by reason of thefact that. the discharge f2() is open. Valve 7 now being closed andvalve .(5 open the water will under valve (l, through the sleeve l2 thetube l5 and. the ways 34, of the sliding valve i8 of the brush 33forcing the same bach in a rotating manner until it strikes the end 93of the rod 16 and forces said rod the linut ot' .its travel as fixed bythe pin 36, closing the discharge 20 and opening the discharge 29.., theforce of the Water lifting the valve 7 and resistance from the valve 5beingr taken away by the opening of the valve 22 the valve 6 will thenclose upon the sleeve '12. This reciprocal motion of the cleansingmedium can be continued unt-il the tube is thoroughly cleansed or aslong,r as may be de- Sired.

Having described this invention in connection with a number ofillustrative embodiments1 forms, proportions and arrangements of parts,to the details of which diS- closure the invention is not ot course. tohe limited, what is claimed as new and what. is d Amircd to be securedby Letters Patent is setorth in the appended claims.
